The importance of the DAX in the financial system and its mode of action

The financial market is a complex system in which countless transactions, speculations and investments take place every day. Indices play a central role here, as they reflect the development of the stock markets in a simplified form and provide orientation. One of the most important German indices is the DAX, which fulfills a variety of functions and at the same timeComposition and development significantly influences the mood on the stock exchanges. This article gives a comprehensive insight into the functioning of the DAX, its importance for the financial world and the mechanisms behind its course system. It explains how the index is formed, which factors determine its development and why it is more than just one todaystatistical tool.

The basic building of a stock portfolio and its development

When a person buys shares from several companies, this is called a so-called stock portfolio. This portfolio is a compilation of different securities, the total value of which changes over time. The performance of the entire portfolio depends largely on how the individual stocks develop. If all stocks in the portfolio increase at the same time,the total value inevitably increases, while at the same time the price drops also decrease. But in reality, the price development of the individual stocks is rarely synchronous, rather they move differently. Thus, the shares of a company A, B and C may rise in value, while another company’s stock D decreases sharply over the same period,Which weakens the entire portfolio accordingly. It is also possible that the stock D is only slightly in value, but the portfolio contains a large number of items, which significantly affects the change in value of the portfolio. The change in the total value depends on two factors: the share that each share has in the portfolio and the respective price development. becomes oneStarting basis, for example a value of 100, one can calculate the continuous development of this value by using a weighting method. The result is an index that reflects the performance and thus reflects the market movements.

The origin and basic principles of the DAX

The best-known German stock index, the DAX, reflects the performance of the 30 stocks most traded companies. As these companies trade on the stock exchange, this index is a pure stock market index that reflects the price development of these companies. The weight of the individual companies in the index is not only based on the number of shares,but rather according to their so-called market capitalization. This is determined by multiplying the number of shares in a company in free float by the current stock market price. This market capitalization gives an approximate value of the importance of a company compared to the other companies included in the index. The weight of eachCompanies in the index are regularly recalculated using these market capitalizations, so that the shares fluctuate daily and adapt to the current market conditions. On a certain day, the weighting of a company like Adidas can be 2.39 percent, for example, while Allianz is 7.28 percent and Volkswagen is 3.30 percent. Change these distributionsHowever, because prices change daily and the shares in free float are also shifted through investments, sales or acquisitions. It can happen that a company is excluded from the index because its market value has fallen so much that it no longer meets the criteria, while other smaller companies move up and include the indexbecome.

The DAX as a symbol of market development and its social importance

However, the DAX is not just a simple summary of the price development of its underlying stocks. A much deeper meaning has developed for the financial world, which goes beyond the pure information function. The index has become a symbol that reflects and influences investors’ moods at the same time. He has taken on a fetish character thatis comparable to the adoration of a golden calf, around which the stockbrokers regularly gather and around which they dance around with fervor. This symbolic power means that the DAX is hardly just considered a statistical variable, but rather as a kind of guiding star on which the expectations and mood of the market participants are based. For investors and fund managers, theDAX a benchmark, a benchmark against which one’s own performance is measured. The goal is to beat the index to be considered a successful investor. Even losses are put into perspective in this context if they are lower compared to the DAX. In practice, the DAX is also used as a basis for replicating with financial products. With the help of suchProducts related to the index can weight their investments accordingly and thus replicate the most accurate possible mapping of the index. This replica is done by so-called funds, which are intended to reflect the development of the DAX one to one, although technical and practical restrictions are always present.

The DAX in the context of the derivatives and speculative financial instruments

The DAX is also an important underlying for a large number of derivative financial products. These products, such as options and futures, are based on the mathematical basis of the index and allow traders to speculate on future price development without directly owning the underlying stocks. In the case of an option, one acquires the right to the Dax to a previously agreedBuy or sell course in the future, while a future is committed to buying or selling the index at a certain price at a specified time. These instruments offer a variety of ways to control risks, maximize profits or rely on falling prices. The close links between the DAX and the derivativesmake the index a central element in the speculation and hedging market. The use of these instruments makes the market even more liquid and dynamic, but at the same time the complexity and the risk of suffering significant losses through unthinking business increases. The close interlocking between the index and derivatives shows how much the modern financial markets are due to technicalModels and mathematical methods are shaped that build on and reinforce the movements of the DAX.
